We report, to the best of our knowledge, the first monolithic visible fiber laser pumped by a pigtailed diode. The robust cavity design proposed is based on a highly reflective fiber Bragg grating spliced to a double-clad praseodymium-doped fiber. The laser signal generated at 635.5 nm is single-mode, has a FWHM bandwidth of 0.16 nm, and reaches a maximum cw output power of 2.3 W. This demonstration breaks ground for the development of reliable high-power visible fiber lasers.

在可见光下工作的2.3 W单片光纤激光器

据我们所知，我们报告了由尾纤二极管泵浦的第一台单片可见光纤激光器。提出的鲁棒腔设计基于拼接到双包层掺fiber光纤的高反射光纤布拉格光栅。在635.5 nm处产生的激光信号是单模的，FWHM带宽为0.16 nm，并且最大cw输出功率为2.3W。该演示为可靠的高功率可见光纤激光器的开发打下了基础。
